i asked and did exactly the same a good few years back, cutting to the chase i bought a tamiya mad bull… and it is brilliant.
i was worried that an electric car would be sluggish and slow, like the completes i had biought the boy previously, but wven with the stock motor its crazy fun fast. an upgrade motor, unnecessary, would be really fun.
i’ve asked about nitro a few times, i like the idea of it because the one negative of the tamiya is that the run time is not that great so multiple batteries are a must, but the general consensus is that its a faff unless you enjoy constant maintenance.
buildwise the tamiya was great, i did it with whisky on boxing day afternoon, and my boy loved painting the car shell and applying stickers. i would buy one again definitely.
